What is the slope of the line for (-2,2) and (2,3)?

Allushta [10]

Answer:

y=1/4x slope is 1/4

Step-by-step explanation:

add 1 to 2 to get 3 for the change in y, then add 4 to -2 to get 2 for the change in x, then put the change in y (1), over the change in x (4), to get a slope of 1/4

Answer: The value of test statistic is 0.696.

Step-by-step explanation:

Since we have given that

$n_1=1399\\\\x_1=411\\\\p_1=\dfrac{x_1}{n_1}=\dfrac{411}{1399}=0.294$

Similarly,

$n_2=759, x_2=211\\\\p_2=\dfrac{x_2}{n_2}=\dfrac{211}{759}=0.278$

At 0.01 level of significance.

Hypothesis are :

$H_0:P_1=P_2=0.5\\\\H_a:P_1\neq P_2$

So, the test statistic value would be

$z=\dfrac{(p_1-p_2)-(P_1-P_2)}{\sqrt{\dfrac{P_1Q_1}{n_1}+\dfrac{P_2Q_2}{n_2}}}\\\\z=\dfrac{0.294-0.278}{\sqrt{0.5\times 0.5(\dfrac{1}{1399}+\dfrac{1}{759})}}\\\\z=\dfrac{0.016}{0.023}=0.696$

Hence, the value of test statistic is 0.696.
